I COOKING STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 605,897, dated June 21,1898.

Application filed June 10 1895.

To all whom it may concern:

Be itknown that I, JOHN J. MCGUFF, a citizen of the United States ofAmerica, residing in Lexington, in the county of Fayette, in the Stateof Kentucky, have invented new and useful Improvements in Cooking-Stovesor OOOkingRanges, of which the following is a specification.

This invention relates to an improvement in cooking stoves and ranges,and has for its object to simplify and improve the construction thereofwith a View to reducing the cost of manufacture, while at the same timeincreasing the life and durability of the stove.

The principal object of the present invention is to connect the oppositeedges of asheetmetal oven with the frame of the stove in such manner asto provide for the expansion and contraction of the oven.

The invention also contemplates binding the edge of the oven between anintegral flange of stove-frame and a separable frame, which partiallysurrounds the oven-plate adjacent to its edge and is bolted to the saidstove-frame.

The invention also contemplates expanding the frame-pieces of the stoveadjacent to their upper ends in such manner as to widen the flue andafford increased area and heating-surface to the top of the oven.

Other objects and advantages of theinvention will appear in the courseof the subjoined description.

The invention consists in certain novel features and details ofconstruction and arrangement of parts, as hereinafter fully described,

illustrated in the drawings, and finally incorporated in the claims.

In the accompanying drawings, Figure 1 is a perspective View of acooking-stove, the top plate and other parts thereof being removed toshow the interior construction. Fig. 2 isa vertical section through thesame. Fig. 3 is a vertical sectional view showing the manner of securingthe edges of the oven-plate. Fig. 4 is a detail perspective view of thedetachable binding-frame of this invention.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings. a

The improved cooking-stove contemplated Serial No. 552,262 (No model.)

in this invention comprises two similar end frames 1, substantiallyrectangular in form, but having their upper forward cornerscorrespondingly cut out for the purpose of providing for theintroduction of theflre-grate, &c. One or both of the said frames arealso provided with a door-opening 2, corresponding in shape to thegeneral configuration of the frame and either partially or whollysurrounded by an integrally-formed flange 3, which extends inwardly andhas its outer edge or face beveled, as shown.

4 designates a pair of frames which may be either of wrought or castiron and which approximate closely the configuration of the flange 3referred to, said frames being, however, made of greater width than saidflanges and of a size which will adapt them to extend around saidflanges and leave an intervening space constituting a groove, in whichthe edge of the oven sheet or plate may be inserted. The oven 5is formedfrom asingle pieceof sheet steel or iron or may be cast,'if preferred,and is formed to correspond with the shape of the integral flange 3 onthe framepieces of the stove, and the opposite side .edges thereof areinserted into the space between the flange 3 and the separable frame 4,as shown in Fig. 2. Each of the-bindingframes 4 is provided at suitableintervals with integral twin lugs 6, arranged in pairs and adapted toreceive between them-suitable bolts, which pass through correspondingopenings in the stove sides or ends, whereby the said frame may be drawntightly against the interior surface of the stove, as shown in Fig. 3.Each of the binding-frames 4 is fur ther provided at suitable intervalswith beveled notches 7, which register with a corresponding series ofinwardly-projectingtapering spurs 8, so that as the binding-frame 4 isdrawn against the inner face of the stove it is simultaneously pressedinward toward the integral flange 3 referred to for more firmly bindingthe edge of the oven' sheet or plate in place. The construction abovedescribed thus permits the opposite edges of the oven to have a slightsliding movement between theflanges 3 and binding-frames 4: and providesfor the necessary traction of said oven.

expansion and con:

IOO

The side or end frame-pieces of the stove are extended laterally inopposite directions, as indicated at 9, for the purpose of increas ingthe width of the flue-space immediately above the oven and also for thepurpose of affording increased area, capacity, and heating-surface tothe top of the stove.

In putting the oven in place and connecting the end frames 1 thereto thebindingframes 4 are first attached loosely to said frame-pieces and theedges of the oven-plate then inserted into the grooves or spaces betweenthe integral flanges and said bindingframes. The frame-pieces 1 are nowforced toward each other with the required pressure and the stove-boltstightened, thereby causing said binding-frames to press inward andconfine the edges of the oven tightly between them and said integralflanges, after which the usual top, sides, and bottom of the stove maybe applied in a manner well understood. It will thus be seen that ampleprovision is made for the expansion and contraction of the oven, andthis will add greatly to the life and durability of the stove. Thebindingframes at the same time prevent ashes, soot, &c., from gettinginto the oven. By making the binding-frames independent of and separable from the frame of the stove and the oven the stove may be set upin a shorter space of time and the cost of manufacture iscorrespondingly cheapened. The increase in the width of the flue-spaceabove the oven also affords an enlarged heating-surface to the stove-topand increases the capacity and utility of the stove correspondingly.

It will be apparent that any desired material may be employed in theconstruction of the several parts of the stove hereinbefore describedand that the same may be either cast or wrought or formed from sheetmetal.

Changes in the form, proportion, and minor details of construction mayberesorted to without departing from the spirit or sacrificing any of theadvantages of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. In a stove, the side or end frame-pieces thereof provided withinwardly-extending flanges corresponding approximately to theconfiguration of the oven, in combination with an oven sheet or platedisposed around said flanges, and separable binding-frames surroundingsaid oven, said frames being arranged in approximal relation to theedges of said oven sheet or plateand secured to the stove-frame,substantially in the manner and for the purpose described.

2. In a stove, the end frame-pieces thereof provided with integralinward]y-projecting flanges corresponding to the configuration of theoven, in combination with an oven plate or sheet extending around saidflanges, and separable binding frames extending around said oven andremovably secured to the stoveframe, said bin din g-frames being formedwith tapering notches which cooperate with beveled or inclinedinwardly-projecting spurs on the stove-frame, substantially in themanner and for the purpose specified.

3. The combination with a cooking-stove having its side plates providedwith bolts adjacent to the oven-space, of a sheet-metal oven composed ofa single sheet of metal corresponding to the contour of the oven-space,and binding-frames extending continuously about the exterior of the ovenon each edge thereof, said binding-frames being formed with lugs to takeover the bolts of the side plates, substantially as set forth.
